Study on Fault Diagnosis of Sliding Bearings Using AE Signals

QIN Ping, YAN Bing, TAN Da ming (School of Mechanical Eng., Southwest Jiaotong University, Chengdu 610031, China)  
Acoustic emission (AE) is used to detect contacting fault of sliding bearings. The contacting fault was simulated on a sliding bearing by gradually reducing the oil supply until no oil being supplied. AE signals were recorded during the simulation for analysis. The results indicate that AE signals are sensitive and quick response to the changes in the working condition of sliding bearings, good in anti disturbance and easy to install, showing a prospect to be applied to fault diagnosis of sliding bearings.
